This invention relates to devices for holding a picture tube in a television cabinet and, more particularly, to such devices for holding the more recent form of picture tube which is provided with an integral implosion shield.

An object of this invention is to provide a new and improved device in the form of a flexible catch for holding a picture tube with an integral implosion shield to the cabinet of a television set.

Another object of the invention isito provide means for holding a picture tube with an integral implosion shield to the cabinet of a television set including flexible members on the cabinet and engageable behind the im-` plosion shield.

Still another object of the invention is to provide a molded flexible catch member either formed integrally with a molded cabinet or interlocked with the cabinet having a generally planar body with the catch member having means defining an opening within the perimeter of the body adapted to receive a peripheral part of the implosion shield and a flexible tab on the body coplanar therewith and extending into said opening adapted to be flexed out of the plane of the body and resiliently engage behind the peripheral part of the implosion shield.

Further objects and advantages will become apparent from the following detailed description taken in con# nection with the accompanying drawings in which:

FIG. l is a fragmentary perspective view of a part of a television set showing a portion of the cabinet front and the interior of the set immediately to the rear thereof;

FIG. 2 is a section taken generally along the line 2-2 in FIG. 1;

FIG. 3 is a fragmentary section taken generally along the line 3-3 in FIG. 2;

FIG. 4 is an elevational view of another form of tube holding device shown in association with a cabinet and a picture tube with a part of the cabinet shown in section;

FIG. 5 is a fragmentary section taken generally along the line 5 5 in FIG. 4;

FIG. 6 is an exploded View of the structure shown in FIG. 7; and

FIG. 7 is a fragmentary perspective view of the catch member and mounting panel of FIG. 4 taken looking from the right-hand side of FIG. 5.

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail an embodiment of the invention together with modifications thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated. The scope of the invention will be pointed out in the appended claims.

Picture tubes for television sets are now available in which a tube 10, as shown in FIGS. 1 and A3, has an integral implosion shield 11 across the front face of the tube with the implosion shield bonded to the tube by the use of suitable bonding material 12. As shown, particularly in FIG. 3, the thickness of bonding material 12 is such as to space the implosion shield from the tube with this space being utilized in the present invention.

A television set, as shownin FIG. 1, has a cabinet, indicated generally at 15, with a front wall 16, a top wall 3,283,072 Patented Nov. l, 1966 "ice 17, and a side wall 18, which, with other cabinet structure, fo'rm' a total enclosure for the tube and other set components. The front Wall 16 has a continuous ange 19 which defines an opening for the viewing of the picture tube. v l

In the embodiment of FIGS. 1 to 3, the cabinet, or masking unit therefor, can be formed of molded material, with the catch devices for the picture tube being molded integrally therewith.

There are preferably four catch devices located at the rounded corners ofthe picture tube with the catch device associated with one corner being shown in the drawings. This catch member comprises a generally planar body 20 secured at its base to the cabinet by being lintegrally molded therewith. The body has means defining an interior opening 21 intorwhich a peripheral part of the implosion shield rim 22 extends. A tab 23 formed integrally with the body of the device and coplanar with the body is then flexed to be positioned behind the rim 22 of the implosion shield and be located in the space be-` tween the shield and the tube and actually lock in behindy the shield rim 2.2. Due to the flexure of the tab 23, and the resilient nature of the tab, the picture tube is resiliently urged against the flange 19 of the cabinet. An example of suitable material for the catch members is molded polypropylene which, when molded, has structural strength, but is flexible.

In the embodiment shown in FIGS. 4 and 5, the catch member is formed for interlocking attachment to a mounting panel of a television set, with the panel being indicated at 30 and the catch member indicated generally at 31. Again, the catch member has a body 32 formed of molded flexible material with an interior opening 33 to receive the rim 22 of the picture tube. The coplanar tab 34 can be flexed to engage behind the implosion shield. In this embodiment, the base of the body is formed as a T by U-shaped notches 36 and 37 resulting in flanges 38 and 39 respectively, engageable with one side of the panel 30. A suitable generally C-shaped opening is formed in the panel for receiving the catch member 31, with the body being held upright by engagement of a panel surface 40, intermediate the ends of the C-shaped opening, with one side of the body and panel surfaces 41 and 42 at the ends of the C-shaped opening engaging with the opposite side. The member is also held in position by the legs 38 and 39, respectively, engaging one side of the panel 30 and by projections 43 and 44 eX- tending outwardly from the plane of the body 32 engaging the other side of the panel.

In the embodiment of FIGS. 4 and 5, the catch member additionally provides a resilient cushion for the picture tube by having a projection 45 on the body at a level to lie between the panel 30 and the implosion shield 11, as shown in FIG. 5.

With the foregoing disclosed structure, it is possible to quickly position a picture tube within the cabinet of the television set by flexing the body of the catches and then holding the picture tube in position by flexing the tab 23 or tab 34 of the catch members to aposition behind the implosion shield which then resiliently locks the tube in position.

We claim:

1. In a television set having a cabinet and a picture tube with an integral implosion shield, means for holding the tube to the cabinet comprising, a plurality of members fixed within the cabinet, each of said members being flexible and having means defining an interior opening for receiving a portion of the periphery of the implosion shield, and a coplanar tab on each of said members extending into the opening and engageable behind the implosion shield for locking the member to the tube.
